Erhard, altitude can be a problem. It affected me for several days when I did that hike.
I would not climb Whitney and then head back down to Guitar Lk. to retrieve my tent.
You can even camp on on the summit of Mt Whitney (carry 3 liters of water from Guitar Lk).
If you leave your pack at the junction of the JMT and the main Mt Whitney trail, put all your food in a rodent-proof container, outside your pack. Squirrels and marmots will chew through the pack.
